Snapshot hub

This is a hub for Snapshot network that stores the database and forwards new messages to peers. The hub holds a private key to sign valid messages.

Install

1. Install Node.js, clone the repository, then say:

yarn

2. Copy .env.example, rename it to .env and set a value for these config vars:

• HUB_DATABASE_URL: The database connection string. You will need to run your own MySQL database or use a Cloud service like JawsDB.
• SEQ_DATABASE_URL: We now use messages from a different database, it can be same as HUB_DATABASE_URL in your local
• RELAYER_PK: This is the private key of the hub. The hub counter-sign every accepted message with this key.

3. Create the database schema

Run this query on the MySQL database to create the initial schema with the required tables: https://github.com/snapshot-labs/snapshot-hub/blob/master/src/helpers/schema.sql

Run

• Use this command to run the hub:

yarn start

• Go on this page: http://localhost:3000/api if everything is fine it should return details of the hub example:
